DIY Help Needed! What can I do with what I have?

Thanks for pointing that out...That being said I think Ill still get four qb288s and add them to my existing 12 cob fixture to supplement and add some new tech to play with. Ill upgrade my drives a little later.Am I looking at wrong thing when I see the H185-1400 driver rated a 202w?

You're not looking at the wrong thing. However you can't max out the load to reach that wattage with 2 QB 288 wired in series to that driver.

To get near that wattage, you would need to be closer to the drivers maximum output voltage of 143 volts (rather than only 70% or a little more of the way there).
